Bullying by FNB Freezing Accounts for Administrative Reasons

I attempted paying at a vendor only to find out I cannot. In fact I can't do any transactions, my bank account is frozen. Why? It turns out after engaging on "secure chat" that there is some outstanding compliance documentation. So, this is how the bank deals with an account that is supposedly mine, containing my money, in my name for which I comp**** in full to have and am paying a monthly fee, interest rates, etc. Now, for some compliance documents that they need my entire bank service is frozen. I can't pay with my phone as it deregistered the service and won't register saying "the service is no presently available". There I am standing in a long line, embarrassed not able to pay. Thank you FNB. I am on the phone to *** with a message "where experiencing higher than normal call rates" I have been on for a long time with no one answering. I am not able to resolve this via secure chat, which is an almost useless service, because they can't really do anything for you. I am a private wealth customer. What does that even mean to you, I think absolutely nothing! It's a shame to think I am baking with you.
